SBF Premium Flexplate 164 Tooth Int. Balance

The TCI SBF Premium Flexplate 164 Tooth Internal Balance is a precision-engineered flexplate designed for Small Block Ford engines requiring neutral balance characteristics. This 164-tooth flexplate serves as the critical mechanical link between your engine and automatic transmission, engineered to handle the torque and rotational demands of high-performance and street applications. Built from steel with internal balance specifications, it integrates seamlessly with the 11.5-inch bolt circle pattern standard to SBF configurations.

Internal balance flexplates distribute rotating mass more evenly across the assembly, reducing vibration and extending the service life of transmission input shafts and related drivetrain components. The 164-tooth count specifies compatibility with modern high-torque starter motors commonly found in performance and street rod applications. TCI's premium construction emphasizes dimensional consistency and material integrity—critical factors since flexplate runout directly affects driveline balance and transmission bearing longevity. At 6.55 lbs, this component is engineered for durability in applications ranging from mild street engines to aggressive naturally aspirated builds.

This flexplate is ideal for SBF engine swaps, restorations, and performance builds where OEM or worn units require replacement. Street rod builders, engine rebuilders, and enthusiasts performing transmission work rely on quality flexplates to maintain driveline integrity during cold starts and under load. The neutral balance specification ensures compatibility with both standard and custom crankshaft assemblies that have been balanced to modern standards, making it a core component in any SBF automatic transmission installation.

When selecting a flexplate, verify your engine's balance type (internal or external) and crankshaft bolt pattern—the 11.5-inch bolt circle and neutral balance designation of this TCI unit align with most modern Small Block Ford applications and standard automatic transmission converters. Proper installation with correct fastener torque specifications is essential to prevent slippage and maintain concentricity.
